原理:執(zhí)行第二個(gè)方法的時(shí)候,取消第一次的方法操作
- (void)viewDidLoad { [super viewDidLoad]; //點(diǎn)擊事件 UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fun1)]; //單點(diǎn)觸摸 tap.numberOfTouchesRequired = 1; //點(diǎn)擊幾次,如果是1就是單擊 tap.numberOfTapsRequired = 1; [self.view addGestureRecognizer:tap]; UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fun2)]; tap2.numberOfTapsRequired = 2; [self.view addGestureRecognizer:tap2]; //如果滿足第二次 第一次的就取消 [tap requireGestureRecognizerToFail:tap2]; }
